Solve A x= b by finding coefficients for the columns of A which show b lies in their span. When solving Ax = b the solution x can be determined by determining the linear combination of the columns of A which equal b. In the interactive cell below A, represents the first column of A while A, represents the second column of A. Determine values of x1 and x2 so that X1A1 + X2A2 = b
